NGI with sub-contractor FRAMO were engaged by Ørsted for the suction operations during the installation campaign from GeoSea's "Innovation" heavy lift vessel.

On 30 July 2018, the last of 20 Suction Bucket Jackets (SBJs) was installed at Ørsted's Borkum Riffgrund 2 Offshore windfarm in the North Sea off the coast of Niedersachsen in Germany.

NGI with sub-contractor FRAMO were engaged by Ørsted for the suction operations during the installation campaign from GeoSea's "Innovation" heavy lift vessel. The detailed geotechnical design of the bucket foundations was performed by NGI team in Oslo in close cooperation with Ørsted. The multidisciplinary engagement in the project also included design and installation of comprehensive Structural Health Monitoring (SHM) systems on two of the jackets to monitor and verify behaviour of the structures during operation in the field.
